m6A Modification:
m6A Regulator Insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) READER
m6A Target Homeobox protein Hox-A13 (HOXA13)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type Histone modification (HistMod)
Epigenetic Regulator PHD finger protein 20 (PHF20) READER View Details
Regulated Target Histone H3 lysine 4 trimethylation (H3K4me3) View Details
Downstream Gene METTL14 View Details
Crosstalk Relationship Histone modification  →  m6A Enhancement
Crosstalk Mechanism histone modification indirectly regulates m6A modification through downstream signaling pathways
Crosstalk Summary PHF20 elevated METTL14 expression by enhancing the enrichment of Histone H3 lysine 4 trimethylation (H3K4me3) on its promoter, and METTL14 strengthened Homeobox protein Hox-A13 (HOXA13) m6A methylation to maintain HOXA13 mRNA stability through IGF2BP3. In conclusion, PHF20 elevates METTL14 expression by enhancing H3K4me3 enrichment on its promoter and enhances HOXA13 mRNA stability via IGF2BP3-mediated m6A modification, thus facilitating HOXA13 expression and eventually inducing osteogenic differentiation of BMSCs.
